Hello there. We have a policy to NOT delete topics, and we stick to that 99% of the time. When you searched for the topic, it sounds like you didn't do a *full* search. Go to the Internet and Browsers forum. Scroll down to the bottom of the main page. Underneath the bar where it shows that you are in the Int. and Browser forum, you will see three boxes with a drop down arrow. They should say "Order: Last post", "Z-A" and "From: 30 Days". In that "From: 30 days" box, click the drop down arrow and change it to "From:60 days" or even "From:90 days".
If for some reason you still can't find it, I may be able to help you. It is possible the thread could have been moved to a different area. Do you remember the topic title? Or the user name of the person who started it? Even a good description of the main post might help!
